Bird ID - Philadelphia Zoo

Female Silver-beaked Tanager I think.

@red river hog Hmmm, I think females are supposed to be redder than this?

In case this helps, the birds signed in the exhibit were Oriental White-eye, Common Bulbul, Blue-gray Tanager, Chinese Hwamei and Red-whiskered Bulbul. But I couldn't find a match. I saw all except the Common Bulbul.

@SusScrofa Maybe a juvenile then? It doesn't seem match any other species that I know to be the bird house.

@SusScrofa They also sometimes rotate individuals between different exhibits. That one had a few other species in it on my visit in March.

I'm inclined to agree with female/juvenile Silver-beaked Tanager - they're not always on the redder side.
